Still heads are designed to connect a flask to a condenser in distillations. The simplest (1) allows a thermometer to be attached to follow the temperature of the distillate. The Claisen still head (2) has an additional socket to allow a dropping funnel or mechanical stirrer to be fitted. The splash head (3) is used to prevent the 'raw' distilling liquid from carrying over into the vapour. This type of still head is often used in steam distillations.
